Definition
Traction is the application of a pulling force to a part of the body
History The use of traction dates as far
back as 3000 years ( ancient
Egyptians ).
Hippocrates (350BC) wrote about
manual traction and the forces of
extension and counter extension.
Guy de Chauliac (1300-1368)
introduce the continuous traction
Used extensively in civil war for
fractured femurs
General Considerations
Safe and dependable way of treating
fractures for more than 100 years
Bone reduced and held by soft tissue
Less risk of infection at fracture site
Allows more joint mobility than plaster
Purpose of traction
To regain normal length and alignment of involved bone.
To reduce and immobilize a fracture bone
To relieve or eliminate muscle spasm.
To relieve pressure on nerves.
To prevent or reduce skeletal deformities or muscle contractures.
DisadvantagesCostly in terms of hospital stay
Hazards of prolonged bed rest
DVT/Thromboembolism
Pneumonia
Requires continuous nursing care
Can develop contractures
Types(based on method)
Manual traction
Skin traction
The traction force applied over a large area of skin. Adhesive and Non-adhesive skin tractions.
Skeletal traction
Applied directly to the bone either by a pin or wire through the bone. (eg- Steinmann pin, denham pin, kirschner wire)
Types(based on mechanism)
Fixed tractionby applying force against a fixed point of body.
Ex: fixed traction by Thomas splint.
Sliding traction
by tilting bed so that patient tends to slide in opposite direction to traction force.
Ex: Hamilton Russell traction.
Perkins traction.
Principles Of Effective TractionCounter traction must be used to achieve
effective traction.
Counter traction is the force acting the
opposite direction .
Usually, the patient's body weight and bed
position adjustments supply the needed
counter traction.
Management of Patients in
TractionCare of the patient
Care of the traction suspension system
Radiographic examination
Physiotherapy
Removal of traction
SKIN TRACTION The traction force is applied over a large
area, this spreads the load and is more comfortable and efficient.
Force applied is transmitted from skin to the bones via superficial fascia, deep fascia and intramuscular septa
For better efficiency the traction force is applied only to the limb distal to the fracture
Weight
Skin damage can result from too much of traction force.
Maximum weight recommended for skin traction is 6.7 kgs
depending on size and weight of the patient
Application Adhesive skin traction :
Prepare the skin by shaving as well as washing & applying tincture benzoin which protects the skin and acts as an additional adhesive.
Avoid placing adhesive strapping over bony prominences, if not, cover them with cotton padding and do the strapping.
Leave a loop of 5 cm projecting beyond the distal end of limb to allow movement of fingers and foot.
Non adhesive skin traction
Useful in thin and atrophic skin.
Frequent reapplication may be
necessary.
Attached traction wt. must not be
more than 4.5 kgs.
Indications
Temporary management of neck of femur fracture.
Femoral shaft fracture in children.
Un displaced fracture of acetabulum.
After reduction of dislocation of Hip.
To correct minor fixed flexion deformities of hip and knee.
Contraindications
Abrasions and lacerations of skin in the area to which traction is to be applied
Varicose veins, impending gangrene
Dermatitis
When there is marked shortening of the bony fragments as the traction weight required is greater than which can be applied through the skin
Complications
Allergic reactions from the adhesive material
Blister formation and pressure sores from slipping
straps
Compartment syndrome from over-tight wrap
Peroneal nerve palsy from wraps about the knee
SKELETAL TRACTION It may be used as a
means of reducing or
maintaining the
reduction of a fracture
It should be reserved for
those cases in which skin
traction is
contraindicated
Steinmann Pin Rigid
stainless steel pins of
varying lengths 4 – 6 mm
in diameter. Bohler stirrup
is attached to steinmann
pin which allows the
direction of the traction to
be varied without turning
the pin in the bone
Denham Pin Identical to
stienmann pin except for
a short threaded length in
the center . This threaded
portion engages the
bony cortex and reduce
the risk of the pin sliding.
Used in cancellous bone
like calcaneum and
osteoporitic bones.
Kirschner wire They are
easy to insert and
minimize the chance of
soft tissue damage and
infections, It easily cuts
out of the bone if a
heavy traction weight is
applied, Most commonly
used in upper limb eg.
Olecranon traction
Application
Use GA or LA.
Paint the skin with iodine and spirit.
Mount the pin/wire on the hand drill.
Hold the limb in same degree of lateral rotation as the normal limb and with ankle at right angles.
Identify the site of insertion and make a
stab wound.
Hold the pin horizontally at right angles to
the long axis of the limb.
Apply small cotton woolen pads soaked in
tincture around the pins to seal the wound.
The pin should pass only through skin, SC
tissue and bone avoiding muscles and
tendons.
Complications
Introduction of infection into bone.
Distraction at fracture site.
Ligamentous damage.
Damage to epiphyseal growth plates.
Depressed scars.
Specific Tractions
Head Halter tractionSimple type cervical traction.
Management of neck pain.
Weight should not exceed 2.3
kg.
Can only be used a few hours
at a time.
Perkin’s traction
Treatment of fractures of tibia and of the femur from the subtrochantric region distally.
Basis of management is the use of skeletal traction coupled with active movements of the injured limb.
Upper Femoral Traction
Lateral traction for fractures with medial or anterior force.
Stretched capsule and ligamentum teres may reduce acetabular fragments.
Ninety-Ninety Traction
Useful for subtrochantric and
proximal 3rd femur fracture.
Especially in young children.
Matches flexion of proximal
fragment.
Can cause flexion contracture in
adult.
Modern Techniques
Traction procedures are
largely replaced now by
more modern techniques,
but certain approaches
are still used today:
Milwaukee brace/ Bryant's
